CORRECT USE OF THE CAR

DRIVING WITH RAIN
Rain and wet roads can be dangerous.
If the road is wet, the traction between
wheel and asphalt is greatly reduced, thus
increasing the stopping distance and de-
creasing road holding.
Here are a few suggestions in the case of
rain:
– Reduce speed and keep further back
from the vehicle in front.
– Heavy rain also reduces visibility. In
these cases, turn on the headlights even dur-
ing the day to make yourself more visible
to others.
– Do not drive over puddles at high speed
and hold the steering wheel firmly: you may
lose control of the car (aquaplaning).
– Position the ventilation controls for
demisting (as described in the chapter (“Get-
ting to know your car”), to prevent visibili-
ty from worsening.
– Routinely check the conditions of the
windscreen wiper blades.
DRIVING IN FOG
– If fog is very thick, avoid travelling
where possible. If travelling with mist,
ground fog or the possibility of fog banks:
– Drive at moderate speed.
– Also in the day turn on the dipped-beam
headlights, rear fog guards and front fog
lights. Do not use the main-beam headlights.
IMPORTANTIf visibility in some parts
improves, switch off the rear fog guards; the
intense light disturbs the occupants of ve-
hicles behind.
– Remember that fog also involves wet
asphalt, thus greater difficulty in all types of
manoeuvres and longer stopping distances.
– Keep well away from the vehicle in
front.
– Where possible avoid sudden changes
in speed.
– Possibly avoid overtaking other vehicles.
– If the vehicle is forced to stop (faults,
impossibility to continue due to poor visi-
bility, etc.), firstly try to pull off the road.
Then turn on the hazard warning lights and,
if possible the dipped-beam headlights.
Rhythmically sound the horn if you note an-
other car coming.
MOUNTAIN DRIVING
– When travelling down hill use the en-
gine braking by engaging lower gears to pre-
vent the brakes from overheating.
– Never coast down hill with the engine
off or in neutral and especially not with the
ignition key removed.
– Drive at a moderate speed and avoid
cutting corners.
– Remember that overtaking up hill is
slower and therefore requires a greater
length of clear road. If you are being over-
taken on a hill, move over to enable the oth-
er vehicle to pass in safety.

CORRECT USE OF THE CAR
182
Tyres
Check the pressure of the tyres routinely at
an interval of no more than 4 weeks: if the
pressure is too low consumption levels in-
crease as resistance to rolling is higher. It
should be underscored that in these condi-
tions tyre wear increases and vehicle per-
formance is lower, therefore also its safety.
Useless loads
Never travel with an overload in the boot.
The weight of the vehicle (especially in ur-
ban traffic), and its geometry heavily affect
consumption levels and stability.
Luggage/ski racks
Remove the luggage rack or ski rack from
the roof as soon as they are no longer used.
These accessories lower air penetration and
adversely affect consumption levels. When
needing to carry particularly voluminous ob-
jects, preferably use a trailer.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy
therefore, increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels (up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at a
standstill or at idle or high speed: under
these conditions the engine warms up much
more slowly, increasing electrical consump-
tion and emissions. It is therefore advisable
to move off immediately, slowly, avoiding
high speeds. This way the engine will warm
faster.
Pointless manoeuvres
Avoid accelerating when waiting at traffic
lights or before switching off the engine. This
and also double declutching is absolutely
pointless on modern cars and also increase
consumption and pollution.
Gear shifting
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance increases
consumption. In the same way improper use
of a high gear increases consumption, emis-
sions and engine wear.

IN AN EMERGENCY

The front light units contain the front side-
light, dipped beam, main beam and fog
light bulbs.
The bulbs are arranged inside the light unit
as follows (fig. 22a):
(A) Main beam headlights
(B) Sidelights
(C) Xenon dipped beam headlights
(D) Fog lights.
Hereafter you will find, as information on-
ly, the description of the correct procedure
to replace a Xenon light.
To change the bulbs of the sidelights,
dipped beams and main beams it is nec-
essary to remove the cover (A-fig. 22b)
releasing the locking screws (B).
To change the fog lights, remove the cov-
er (C) turning it counter-clockwise.
After replacement, refit
the covers correctly check-
ing that they are properly
secured.
IF AN EXTERIOR
LIGHT GOES OUT
XENON LIGHTS
Xenon lights have a very long life, there-
fore breakdowns are unlikely.

WARNING
Any operation regarding
the front light units shall be
carried out with the lights turned
off and the ignition key removed

After replacement, refit
the covers correctly check-
ing that they are properly
secured.
IMPORTANTOn the inside surface of
the headlight there could appear a slight
coat of fogging; this does not show a de-
fect, since it is a natural occurrence due to
low temperature and to the degree of hu-
midity in the air; it will soon disappear as
soon as the lights are turned on. The pres-
ence of drops inside the headlight shows
water seepage, refer to the Alfa Romeo
Dealership.

IN THE EVENT
OF AN ACCIDENT
– It is important to keep calm.
– If you are not directly involved, stop at
least a few dozen metres away from the ac-
cident.
– On motorways, stop without blocking
the emergency lane.
– Turn the engine off and the hazard warn-
ing lights on.
– At night, illuminate the place of the ac-
cident with the headlights.
– Take care, do not risk being run over.– Signal the accident placing the triangle
at regulation distance in a clearly visible
place.
– Call the emergency organisation, giving
the most accurate information possible. On
motorways use the special phones provid-
ed.
– In motorway pileups, especially with
poor visibility, the risk of being involved in
other crashes is high. Leave the car imme-
diately and go beyond the guard-rail.
– If the doors are blocked, do not try to
get out of the car breaking the windscreen
which is stratified. The windows and rear
screen are easier to break.
– Remove the ignition key of the vehi-
cles involved.– If you note a smell of fuel or other chem-
ical products, do not smoke and have ciga-
rettes stubbed out.
– To put out fires, even small ones, use
the extinguisher, blankets, sand, or earth.
Never use water.
– If use of the lighting system is not nec-
essary, disconnect the battery negative ter-
minal (–).
